Product Details

MPA Electrical NM4199 is a new brake master cylinder built to restore hydraulic braking performance. The unit is tested against OE specifications using controlled inspection and validation processes, helping ensure consistent brake feel and proper fluid delivery after installation. It includes the reservoir, cap, and gasket/seal, while mounting hardware, brake booster, push rod, sensor, and brake pressure switch are not included.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. For shoppers searching for a 2009-2012 Chevrolet Malibu brake master cylinder, a 2009-2010 Pontiac G6 master cylinder, or a 2009 Saturn Aura brake hydraulics replacement, NM4199 is the relevant part number to verify.

What It Helps Address

• Low or inconsistent brake pedal pressure
• Internal master cylinder seal wear
• Brake fluid bypass within the hydraulic system
• Delayed or uneven brake response
• Leaks at the master cylinder reservoir or seal area

Installation Notes

Confirm vehicle fitment by year, make, model, and front disc brake configuration before installation. Bench bleeding the master cylinder before mounting helps remove trapped air and supports proper pedal feel. Use DOT 3 brake fluid only, and inspect brake lines, fittings, and the booster interface during service. Verify the bore size and mounting hole layout match the original unit on your Chevrolet Malibu, Pontiac G6, or Saturn Aura.

Quality Assurance

MPA Electrical uses OE sample references and testing protocols to validate this master cylinder against original specifications. That process supports consistent out-of-box performance for brake system repair and replacement.
